Hi,
I’m selling 4 of my filament cartridges:
- 2x refillable un-opened and sealed (white PLA; marked them outside on the box with my filament serial number
) - 1x refillable opened (just 50g used)
- 1x non-refillable opended but not used
)The price of all four would be 4*29,90 = $ 120 + $ 9 taxes + $32 shipment. ($ 153 on the Zeepro shop)
REFILLABLE ARE NOT AVAILABLE ANYMORE! 
Would sell the cartridges for $ 90 + shipment according to the delivery provider
Just contact me via mail: kontakt@martinlauber.com
